HEATNG DEVICE FOB MANGLES.

Application filed January 19, 1920. Serial No. 352430.

To aZZ whom it may conccrn:

Be it known that I, ARNOLD L. GUESMER, a citizen of the United States residing at Minneapolis, in the County of Hennepin and tate of Minnesota, have invented certain new and useful, Improvements in Heating Devices for Mangles; and I do hereby 'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to ironing machines i of the type usually designated as mangles,

and in which a roller with a pliable facing works against a fixed shoe of segmental form. In these mangles, the shoe has usually been heated by gas supplied by burners located in position to direct the flames onto the shoe; and where city gas, or gas from any gas generating plant is available, the above arrangement has been found satis factory, but in many rural districts, gas is not available and hence, the mangles designed as above stated have not been usable.

Oil stoves, especially kerosene stoves are available and etlicient for use everywhere; and hence my invention provides for the use thereof in connection with these mangles to heat the shoes thereof. In applying the invention, the ordinary gas burner is removed, the shoe is provided with an extended hood, or hot air chamber formed in its bottom with heat passages, and an oil stove is supported under the said hot air chamber or hood in position to discharge its flames or hot gases through the heat passages and upward into the hood, so as to thereby keep the shoe hotand at the desired temperature for ironing.

The invention is' illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. Referrng to the drawings:

Fig. 1 is a perspective View with some parts broken away, illustrating my invention as appled to a mangle or ironing machine of commercial form; and

Fig. 2 is a vertical section taken approximately on the line 2-2 of Fig. l, some parts being broken away.

Of the parts of the mangle, it is only desirable for the purposes of this case to particularly note the supporting table 3, the roller supporting frame 4, the roller 5 and the shoe 6, which parts are of well known Construction and arrangement.

In applying my nvention, the gas burner is removed, and a large hood 7 is applied to the shoe, being preferably clamped thereto by nut-equipped bolts 8. The hood 7 forms a complete hot air chamber closed at top, ende, sides and bottom except for large heat passages 9 provided in the bottom of the said hood. The hood is preferably made up of inner and outer layers of sheet metal and an interposed layer of asbestos, so that the hood will not radiate heat to any considerable eXtent.

The numeral 10 indicates an oil stove, preterably a kerosene stove, which is supported in proper position by a shelf 11 Secured 'to the table structure 3. This oil stove, as shown, has three burners, and hence, the hood 7 is provided with three heat passages 9 in its bottom. These heat passages 9 are located, one directly over each burner of the Gli stove, and preferably the heat passages 9 from the several burners will be discharged directly upward into the interior of the hood 7 and will be carried against the shoe 6, thereby keeping the shoe hot, and at the right temperature for ironing. Of course, the temperature can be varied by regulation or adjustment of the burners of the stove. It is important to note that there is sufiicient clearance between the top of the oil stove and the bottom of the hood to permit the escape of cooler portions of the gases from the interier of the hood. The hot gases or heat from the burners will pass centrally upward through the passages 9 to the top of the hood, and from thence, against the shoe, and will displace the cooler portons of the gases which are at the bottom of the hood, and crowd the same out and downward through the marginal portions of said passages 9. Thiis the gases or heat are confined'within the hood long enough to insure good heating of the shoe 6. In actual practice, the above described heating device has been found highly etficient for the purposes had in view. It may be applied to commercial mangles at small cost, and as stated, extends the use of such mangles to districts where gas is not available.

What I claim is:

1. The combination with an ironing machine comprising an ironirng roller and a chine whereby an oil stove can be disposed with its burners under the said apertures.

'2. The combination with an ironing machine roller and a shoe extending partiaily around said roller at one side thereof, of a hood extending laterally from aid shoe and having a substantially fiat bottom adapted to overhang an oil stove, and having openings in said bottom disposed over the burners of said stove whereby the heat from the stove may pass into said hood and heat said shoe.

3. A means of conclucting and applying to an ironing machine shoe situated vertically at the side of and partially around the cylinder around which the clothes to be ironed move, heat from the cylindrieal burners of an ordinary oil stove, so'that said heat will be applied directly to such shoe which means consists of a hood-chamber of heat insulating material attached to said shoe so that said shoe forms one side of said hood-chamber, and which hoodchamber extends away from said shoe horizontally, and has in its bottom, openings ings in said bottom disposed over the burners of said stove whereby the heat from the stove may pass into said hood and be defiected laterally to heat said shoe.

5. The combination with a roller and shoe of an ironing machine and its support, of a hood detachably Secured to said shoe, projecting laterally in' oti' set relation thereto, substantially all of the hood projecting beyond said support` said hood being wide w and having a curved top, a fiat substantially horizontal bottom and closed ends, forming a heat receiving chamber, and a series of openings in said bottom providing large heat passages through which flames from the several burners of an oil stove may be directed upwardly into said chamber and deflected laterally by the curved top thereof, against the shoe to heat'said shoe.

In testinony whereof I afiix my signature.

ARNOLD L. GUESMER.
